Given numbers are 885,981,545,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 885,981,545,988 is 285922260.
Find LCM of 885,981,545,988 with Prime Factorization
| 3 | 885, 981, 545, 988 |
| 5 | 295, 327, 545, 988 |
| 109 | 59, 327, 109, 988 |
| 59, 3, 1, 988 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 109 x 59 x 3 x 1 x 988 = 285922260
Therefore, the lowest common multiple of 885,981,545,988 is 285922260.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
885 x 981 x 545 x 988 = 467482895100
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
885 : 1, 3, 5, 15, 59, 177, 295, 885
981 : 1, 3, 9, 109, 327, 981
545 : 1, 5, 109, 545
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,981,545,988, is 1.
Now, the common factors can be found like this.
885:3x 5x 59
981:3x 3x 109
545:5x 109
988:2x 2x 13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 109 = 1635
Therefore, the value for common factors is 1635.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 467482895100/(1x1635)
LCM = 467482895100/1635
LCM = 285922260
Thus, we can understand that the LCM of 885,981,545,988 is 285922260.
